This is meant to be used with compatible Flexi Leashes with the attachment slot on the underside. Holds a standard roll of dog waste bags. Works like a charm. I will likely release a generic container to hold treats as well. Uses a threaded cap, available with and without knurling.
Printed in PETG.Should be fine in a variety of plastics. Make sure you are well calibrated so that the threads work out.
